The Dark Knight and it actors. cause and effect?

I think that that is an interesting theory. However, you cannot blame a movie for the death of an actor or the outraging of another. Allbeit sad for his death, it was his choice to do the drugs, right? I think alot of actors have had this problem, they learn to deal with it and you dont hear of them dying from them. This is like the Poltergiest movies. It is a coincidence. Anthony Hopkins never O.D.ed on anything and he played one of the most famous villians of all, Hannibal Lecter. Not only did he do this once, but twice. He never did anything like that at all.
